Artboard size under illustrator object?

Question

Adobe Illustrator

What are the hot keys to fit the size of the artboard to the object?
I know how to do it with pens, but I need it quickly, because there are 50+ such icons

Answer 1

Method number 1
Set up hotkeys in the "Editing -> Keyboard Shortcuts" panel.
Switch to the "Program Menu", enter "fit" in the search and specify the hotkeys specifically for this action
Method #2 (from user RAX7 in the comments to the question)
Object -> artboard -> fit to illustration borders
Double-click on the "Artboards" tool and in the "Settings" box, select "Fit to illustration borders.

Answer 2

If the files are in PDF format. Or you can export/save from Ai to PDF.
If you end up with a bunch of separate files, then make them a separate multi-page one.
Then do everything in Acrobat Pro via Print production -> Preflight
There is a ready-made action - Crop all page to bounding box
